As much fun as it is to try and guess what might be wrong with your 57 Ford ( black) it is sort of like playing the game Battleship. One wild guess after another.

Can you hook up a compression tester and get some reading both dry and wet. POST the results.

Attach a manifold vacuum gage to the engine and leave it on while your car starts and then starts to have its problem(s) POST the results.

Leave a inductive timing light attached and test for regular spark pulse both before and after the problem happens. POST the results.

Throwing new parts at a car will work after some period of time but it will get expensive. Car engines are just air pumps. Put a combustibe gas in and provide a spark at the proper time then allow the spent gas to exhaust, then start the process again.

Give the forum some HARD DATA and you will get more than guesses. Pete
